Faraday’s interrupt controller can function in either Fast Interrupt Request (FIQ) mode or Standard Interrupt Request (IRQ) mode to interact with a host processor. The interrupt controller can handle up to 64 configurable standard interrupt sources and up to 64 fast interrupt sources. The output signals to the host processor can be configured to either active high or active low.

Features :

- Supports APB clock rates of up to 66 MHz
- Controller configurable to support up to 64 fast interrupt (FIQ) inputs
- Controller configurable to support up to 64 standard interrupt (IRQ) inputs
- Handles both edge- and level-triggered interrupt sources
- De-bounce circuit independently configurable to be ON or OFF for each interrupt source
- Interrupt request signal to host controller can be configured to either active high or active low
